摘　　要：针对废杂Cu直接重熔精炼制备黄铜的熔体处理过程,总结了再生黄铜,尤其是再生铅黄铜熔铸过程中覆盖、精炼及变质等技术现状。结果发现,目前缺乏针对废杂Cu再生制备黄铜的高效覆盖剂及精炼剂,变质剂的研究主要集中在B、Ti、Zr、B-Ti-Zr复合变质剂、RE、Ca、P等,并综述了废杂Cu再生制备铅黄铜熔剂的应用前景。Based on the refinement and modification treatment of reclaimed brass melted straight by cop- per scrap, the research status of the covering agent, refining agent and modifiers for reclaimed brass, es- pecially for reclaimed leaded brass, were summarized. The result shows that effective covering agent and refining agent for reclaimed leaded brass are absent recently, while the main modifiers are B, Ti, Zr, B-Ti- Zr composite modifier,RE,Ca,P, et al. The fluxes for reclaimed leaded brass were also prospected.
